    Is there a technical reason for spring units being N/mm for the front springs (but lbf/in for the front third spring), and lbf/in for the rear spring?
    Thanks ans cheers.

    Looks like american designed rear suspension with wrong units :p

    it would be interesting to know if there is any reason for this though,
    I'm sure engineering are competent enough to convert lb/inch to N/mm so why didn't they change it ?

    Maybe something as simple as supply of spare parts. When researching a car(years ago) I found a listing for a LMP that was offered for sale. Even though the car was a European design and build, all the spring spares listed for the sale were in pounds not newtons.
    But as far as mixing the two??? That is wierd. Oreca began to climb the ranks using Dodge/Chrysler Vipers. Then they purchased the Courage(French) team that formed the basis of the very good Acura ARX 01b, which I think was their starting point as they began construct Prototypes. But again, that was French and British engineers....odd the whole thing.

    I see so probably N/mm equivalent of lb/inch springs rate are not available or were not available so they stuck with it.

    Because official Oreca 07 user manual reports those units. So better to ask Oreca, not Studio397
